    • note
    • The double-resonance signal is estimated via a calculation of the decrease in infrared signal intensity as a function of the position of two dressed states with a given interaction matrix coupling element. In Fig. 4(a), the relative frequency position of 0 MHz corresponds to the resonance condition of the two dressed states (see Fig. 2) and thus reflects the position of greatest double-resonance signal modulation.

    • note
    • We note that our instrumental double-resonance linewidth (6 MHz) is less than the predicted value for a 5 MHz infrared linewidth (9 MHz). The infrared linewidth results from residual Doppler broadening in the collimated molecular beam. This lower measured line width suggests that the double-resonance measurements achieve a small sub-Doppler linewidth reduction.

    • The vibrational spectroscopy of molecules with torsional motions is similar to the spectroscopy of weakly bound molecular complexes. However, for single molecules, direct transitions to higher torsional states in the vibrational excited state are typically not observed. In contrast, direct excitation of high-frequency/low-frequency combination bands has been observed for weakly bound complexes, although only with very high sensitivity methods; C. M. Lovejoy and D. J. Nesbitt, Chem. Phys. Lett. 146, 582 (1988).
